Given below are two statements : one is labelled as Assertion (A) and the other is labelled as Reason (R).
Assertion (A) : The metal carbon bond in metal carbonyls possesses both and character.
Reason (R) : The ligand to metal bond is a bond and metal to ligand bond is a bond.
In the light of the above statements, choose the most appropriate answer from the options given below.
- A(A) is not correct but (R) is correct
- BBoth (A) and (R) are correct and (R) is the correct explanation of (A)
- CBoth (A) and (R) are correct but (R) is not the correct explanation of (A)
- D(A) is correct but (R) is not correct

Correct answer: D

In case of metal carbonyls, the bonding has both $\sigma$ and $\pi$ nature, where ligand to metal bond is '$\sigma$' (coordinate) bond and metal to ligand bond is '$\pi$' (synergic) bond.
